STRAINEH FOR FAUCETS.

. I, HENRY MUELLER, a citizen of the United States, residing at De-'catur, in the. county of Macon and State of Illinois, have invented newand usefulImprovements in Strainers for Faucets, of which the followingis a specification.

My present invention relates generally to Be it known that faucets, andmore particularly to a faucet,

having a strainer attachment.

The-object of the invention is to provide a strainer for faucets thateasy and cheap to manufacture, but which will be readily attachable anddetachable.

Briefly and generally stated, the invention resides in a strainer forfaucets comprising .a foraminous sleeve split longitudinally, whereby itmay be easily and quickly insert-' ed into positlon within the hollowshank of the faucet, and which will be retained therethe inherentspringiness of the material from which the strainer is composed, thesaid sleeve being open at one end and closed at the other. The inventionfurther resides in a faucet having its hollow shank provided with acontracted neck at one end to closely embrace the open endof-theforaminons sleeve and with lugs againstwhich the other or closed end ofthesleeve may seat Qwhereby to hold' said end in proper position andprovide for the free passage of water through the faucet Shank. v

-In order to enable others skilled in the art to understand, make anduse my said invention, I will now proceed to describe the same beinghad. for this purpose to the accompanying drawing, in which of a faucethaving one of my improved strainers in position therein. 'Fig. '2 is asection on the line a-a of Fig. 1. Fig. 3

will not only be will be maintained in.

the construction is the same.

numeral 10 designates a faucet of ordina construction, having a hollowexternally threaded shank 12, depending from the base 13, said shankbeing bored out to provide an Patented Jan. 31-, 1911.

enlarged passage 1 4,and a contracted neck" 15., the latter beinglocated at the lower end of the shank.

Within the hollow shank at a cent the. base 13 of the faucet is provideplufiality of laterally extending lugs 16, eac sarily, provided with aseat 17, designed to receive the closed end of the strainer now to bedescribed.

My improved strainer consists of a forami nous metal sleeve ablythroughout its length, and having one of'its endsclosed by animperforate cap 20, while its other end-is left open so thatnormally theadjacent edges of the; sleeve will be slightly separated owing to thespringy nature .of the metal, as .more clearly shown in Fig. 5, butwhich will be brought together when the sleeve is in position withln thefaucet shank.

When in osition for use as 1, the closed the seats 17, formed in thelugs 16, and owing to the angular formation of the seats the upper endof the strainer will be maintained in proper position within the hollowshank and against lateral movement. I wish it understood, however,

shown in Fig.

proper working dispensed with. The is closely embraced 15 at the lowerend ower end of the sleeve by the contracted neck of the point ad'a- 18,split as at 19, prefer end of the sleeve will rest upon that the seats17 are not absolutely essential to a of the device, and 1f referred theymay be hollowshank, and a of whichis preferably, but not necesas thenatural tendency of the split sleeve is to expand against the walls ofthe neck, it

position-by the inherent .springiness of the metal of the sleeve. -InFig. 6 I have illustrated my improved strainer as having aconical forminstead of cylindrical, as in the other figures, otherwise In saidfigure the reference numeral 15; the contracted neck, 16' the lugs, and18 the foraminousconical sleeve constituting the strainer, which splitlongitudinally as at 19;

As will be obvious, may lie-easily inserted in the hollow shank l2designates the fan-.

my improved strainer sleeve is of a faucet of any design, and as readilyre-' moved therefrom for cleaningpurposes, or I,

for purposes of repair.

While I have herein shown the strainer as composed of perforated sheetmetal, it will be obvious that the same may' be formed'of any suitablereticulated materiahthe showing here being merely by way of example.

Inasmuch as the strainer is closed at its upper end, it will be apparentthat as the force of the water therethrough, and through the-shank, isacting directly against said closed end, the head of the column of waterWill tend to retain the strainer in position even though the contractedneck should not embrace the end thereof sullicientlyclose to effect thispurpose. 4

Having thus described my invention, what I claim as ,new and desire tosecure by United States Letters Patent is 1. The combination with afaucet having a shank channel for water, of a compressible strainerpositioned Within said channel, said shank having an outlet and aninletfor the water, said shank being contracted at its inlet end, saidstrainer at one end adapted to fit snugly in the contracted end of saidshank to be compressingly held in position, an imperforate closure uponsaid strainer at its end adjacent the outlet of said channel, and meanscarriedby said shank, abutting upon said imperforate closure, within theplane of said channel, for preventing the displacement of said strainerin the direction of flow of the filtered water.

v 2. The combination with a .faucet having a shank channel for water, ofa resilientstrainer positioned within said channel, said shank having anoutletand inlet for the passage ofwater, said shank being contracted atits inlet end, said strainer engaging the contrac'ted end of said shank,being removably held. against'the walls thereof by its own resiliency,an imperforate closure upon sai strainer at its end adjacent the outletof said channel, and means carried said shank,

, abutting upon said imperforate closure, sub

stantially within the plane of said shank, for preventing thedisplacement of said strainer in thedirection of flow of the filteredwater, said strainer being removable out of theinlet or said shank.

3. The combination with a hollow shank of a compressible strainertherefor, said shank havmg an inlet and an outlet for water and havingat :silient foraminous sleeve,

sure to prevent ,the displacement of strainer in the -tered water.

LlThe combination with a faucet having foraminous resilient sleeve,

, ency,

inlet end a. consaid strainer comprising a reone end thereof adapted tobe fixedly compressed a gainst the 'walls of the contracted neckaforementioned, an imperforate closure upon said'slceve at its endadjacent the outlet of said shank, and inwardly extending lugs carriedby said shank, abutting upon said iinperforate closaid tracted neck,

direction of flow a shank channel for water, said shank having an inletand an outlet for the passage of water and formed at its inlet end witha contracted neck, of a strainer comprising a one. end thereof engagingthe contracted walls of said shank, being removably retained by its ownresilian imperforate cap carried by said sleeve at its end adjacent theoutlet of said 'channel, and a plurality of spaced lugs mounted on saidshank, abutting upon said imperforate cap substantially within theplaneof said channel, for preventing the displacement 'of said strainer inthe direction of .fiow of thefiltered water, said strainer adapted to beremoved from the inlet end of said channel.

5. In combination with a hollow shank having a contracted neck andinwardly extending lugs, a strainer removably supported in said shankcomprising a foraminous sleeve, open at. one end and closed at theother, said sleeve seated at its closed end againstsaid lugs,--andembraced at the opposite end by said neck, pose specified.

6. In combination with a hollow shank having a contracted neck at oneend and lugs at the other, a resilient strainer removably supported insaid shank, comprising a split sleeve of foraminous material, open atone end and closed at the other, said sleeve hearing at its closed endagainst said lugs and adapted to be'resiliently embraced by the walls ofsaid contracted neck at its open end,

as and for the purposes. specified.
